into parts when converting to Unicode.
m_ctype.h:
Reorganizing mb_wc return codes to be able
to return "an unassigned N-byte-long character".
sql_string.cc:
Adding code to detect and properly handle
unassigned characters (i.e. the those character
which are correctly formed according to the
character specifications, but don't have Unicode
mapping).
Many files:
Fixing conversion function to return new codes.
ctype_ujis.test, ctype_gbk.test, ctype_big5.test:
Adding a test case.
ctype_ujis.result, ctype_gbk.result, ctype_big5.result:
Fixing results accordingly.
index doesn't return correct result
item_cmpfunc.cc:
Use charset of LIKE to decide whether
to use 8bit or Unicode "escape" value.
But use charset of "escape" to scan escape character.
strings/ctype-xxx.c:
We cannot reduce "end" pointer using charpos(),
because of possible escape characters in the string.
Limit the loop using count of written characters instead.
ctype_like_escape.inc:
new file
mysql-test/t/ctype_xxx:
mysql-test/r/ctype_xxx:
Adding test case.
In cp932, '\' character can be the second byte in a
multi-byte character stream. This makes it difficult to use
mysql_escape_string. Added flag to indicate which languages allow
'\' as second byte of multibyte sequence so that when putting a prepared
statement into the binlog we can decide at runtime whether hex encoding
is really needed.
ctype-cp932.c:
ctype-gbk.c:
ctype-mb.c:
ctype-simple.c:
ctype-sjis.c:
ctype-ucs2.c:
ctype-ujis.c:
ctype-utf8.c:
Adding explicit cast to return type
in pointer substructions to avoid
warnings from some compilers.
Bug #11987
mysql will truncate the text when the text contain GBK char:"0xA3A0" and "0xA1"
Allow to store and retrieve even unassigned GBK codes.
Like we did in Big5 earlier.
have_gbk.inc, have_gbk.require, ctype_gbk.result, ctype_gbk.test:
new file
New BitKeeper file ``mysql-test/include/ctype_innodb_like.inc''
Many files:
bug#11650: LIKE pattern matching using prefix index doesn't return correct result
min and max values were too long in the case of prefix key.
Fix my_like_range functions not to exceed prefix length.
ctype_innodb_like.inc:
new file
Don't read character set files if we are using only the default charset. In most cases the user will not anymore get a warning about missing character set files
Compare strings with space extend instead of space strip. Now the following comparisons holds: "a" == "a " and "a\t" < "a". (Bug #3152).
Note: Because of the above fix, one has to do a REPAIR on any table that has an ascii character < 32 last in a CHAR/VARCHAR/TEXT columns.
Added more DBUG statements
Ensure that we are comparing end space with BINARY strings
Use 'any_db' instead of '' to mean any database. (For HANDLER command)
Only strip ' ' when comparing CHAR, not other space-like characters (like \t)
sequence boundaries in functions LIKE and LOCATE in
the case of "binary" collation. Comparison was done
like if the strings were just a binary strings without
character set assumption.
